Head-Fier

Hi, i have a pair of hd25 and i love how they sound, punchy bass and forward vocals, but i need something with more soundtage or less thin sound, i only hear electronic music, maximun price should be 350-400usd, i were searching and i found this models: ultrasone hfi-780(which people say are excellent for electronic music), denon d2000. I think both would be an upgrade from hd25, i need to know if vocals are the same forward like in hd25.
Also i tryed westone um3x which im going to buy and are excellent, would be d2000 or hfi-780 at the same level of um3x?
Thanks
